  abstract = {{T}he functioning of tropical coral reefs is imperilled by climate change, overfishing, and decreasing water quality. {M}aintaining their capacity to provide goods and services will critically depend on our ability to monitor their functioning at appropriate spatial and temporal scales. {G}iven the constraints of traditional methods to respond to those needs, the potential of complementary tools such as {P}assive {A}coustic {M}onitoring ({PAM}) is emerging. {C}oral reef soundscapes (i.e. ambient sound) encompass sounds produced by numerous organisms. {S}oundscape characteristics quantified by ecoacoustic indices have been found to reflect general ecosystem properties, such as diversity and abundance of fishes, and coral cover. {T}he present study tested, on the virtually pristine coral reefs around {E}uropa {I}sland, {S}outh-{W}est {I}ndian {O}cean, the capacity of acoustic indices to assess key ecosystem functions. {S}oundscapes were recorded during 2 h, and ecosystem functions were evaluated using video footage of the fish assemblages and underwater photogrammetry of the benthic landscapes. {W}e found significant and strong correlations between six ecoacoustic indices and six key ecosystem functions, including habitat features and fish assemblage characteristics. {T}he six ecoacoustic indices were representative of several combinations of frequency, amplitude and time analysis domains, highlighting the diversity of the functional information conveyed by soundscapes. {O}ur findings reveal that a 2 h daytime recording on a coral reef could provide sufficient acoustic information to characterise major ecosystem functions of a site. {T}his should facilitate the detection of functional disturbances at temporal and spatial scales adapted to the rapidity of upcoming climate changes. {O}ur results also highlight the potential of ecoacoustics to bring novel and relevant insights in the functioning of ecosystems.},
